Abstract: In a method for imaging of a rotogravure form or an imaged rotogravure form, the rotogravure form is imaged by providing cups therein of different dimensions to achieve different tone values or print densities. Image data are assembled from image tiles to provide for the imaging of the rotogravure form. The imaging of the rotogravure form is preferably by engraving.

Abstract: In a method for multi-beam exposure of a printing form, preferably with laser beams, a computer transmits printing form data to a distributor via a data line as a sequence of recording lines and the distributor cyclically distributes the recording lines onto the input stages of an optics head where N parallel laser beams are generated and modulated with the printing form data of the recording lines. The laser beams are subdivided into active and inactive laser beams, recording lines of the printing form are transmitted via the data line for the active laser beams, and empty lines are inserted into the transmitted sequence of the recording lines for the inactive laser beams. The empty lines contain data values with which the inactive laser beams are driven dark.

Abstract: An externally heated hot-runner nozzle for producing injection molded parts has a resistance wire which is composed of an inner electric heating conductor, a ceramic insulating intermediate layer and an outer metal sheath and comprises two end portions to which a heating voltage can be applied, as well as an intermediate section which in the form of a heating coil is assigned to the circumference of the hot-runner nozzle. The resistance wire is characterized in that the two end portions having an outer diameter of 1.5 mm to 2.5 mm are dimensioned to be larger than the intermediate section having an outer diameter of 1.0 mm to 1.8 mm.

Abstract: A test value corresponding to blood subsidence from a syllectogram is determined as a result of the effect of shearing forces on a blood sample, by ascertaining the slope of the test curve representing the syllectogram at a predetermined time beginning with or after the onset of the blood aggregation phase as the test value after:(a) sudden stoppage of the shearing; or(b) a transition to a continuous minor residual shearing.
